Align acquisitions closer to patron needs
With DDA:
- Libraries only pay for titles that reach a threshold of usage, ensuring every acquisition reflects real reader demand, making it a highly efficient and low-risk way to build collections with perpetual access on JSTOR
- Researchers can search across the full text of books, journals, and primary sources on JSTOR, increasing discovery and usage by placing the ebooks into existing research workflows
- All ebook chapters are available exclusively in a DRM-free, unlimited-user model during the access period
- Ebooks come from leading institutions, and work just like journal articles on JSTOR, with unlimited simultaneous use, PDF downloads, and printing, and no need to log in or use special software
How DDA works:
- Select from 149,000+ titles that can be sorted by cost, publisher, copyright year, and discipline
- Exclusive management through GOBI Library Solutions/Mosaic, or Rialto/OASIS
- Consistent ordering, invoicing, and integration with library systems
- Robust, library-driven acquisition models, catalog integration, and discovery across platforms
- Enhanced metadata services and flexible budgeting options
- High-quality MARC records delivery through JSTOR’s partnership with OCLC
